The Last Deglaciation

In the subtropical zone of southern China, there was a considerable conversion of forests from deciduous to evergreen broadleaf in the early Holocene. However, the exact timing of this vegetation change and its relationship to climate are still unclear. We examined a high-resolution pollen record collected in the mid-subtropical zone and then performed a correlation with regional data to reconstruct the history of forest ecosystems since the last deglaciation. Our data show that the expansion of the evergreen plant component already occurred at low elevations during the last deglaciation. The subtropical mountain landscape was not recolonized by evergreen forests until the mid-Holocene at about 8.1 ka BP. Based on fossil pollen reconstruction and climate model simulation, we conclude that the primary increase in evergreen components of subtropical ecosystems was triggered by postglacial temperature increase, and that a complete conversion from deciduous to evergreen forest ecosystems did not occur until Holocene winter temperatures and seasonal temperature contrast reached a threshold suitable for the growth and persistence of evergreen tree species.

Reservoir Age

<p>Paleoclimate records from the North Atlantic show some of the most iconic signals of abrupt climate change during the ice ages. Here we use radiocarbon as a tracer of ocean circulation and air-sea gas exchange to investigate potential mechanisms for the abrupt climate changes seen in the North Atlantic over the last deglaciation. We have created a stack of North Atlantic surface radiocarbon reservoir ages over the past 20,000 years, using new synchronized age models from thirteen sediment cores refined with thorium normalization between tie-points. This stack shows consistent and large reservoir age increases of more than 1000 years from the LGM into HS1, dropping abruptly back to approximately modern reservoir ages before the onset of the Bolling-Allerod. We use the intermediate complexity earth system model cGENIE to investigate the potential drivers of these reservoir age changes. We find that sea ice, circulation and CO<sub>2</sub> all play important roles in setting the reservoir age. We use these coherently dated records to revisit the sequence and timing of climatic events during HS1 and the last deglaciation, and show that Laurentide Heinrich Events are a response to stadial conditions, rather than their root cause.</p>
